TOP Interrupt Control Register 3 (TOPIR3)

<Address: H’0080 0233>

Bit Name

Function

8, 9

No function assigned. Fix to "0."

TOPIS9 (TOP9 interrupt request status bit)

0: Interrupt not requested

R(Note 1)

TOPIS8 (TOP8 interrupt request status bit)

1: Interrupt requested

12, 13

No function assigned. Fix to "0."

TOPIM9 (TOP9 interrupt request mask bit)

0: Enable interrupt request

TOPIM8 (TOP8 interrupt request mask bit)

1: Mask (disable) interrupt request

Note 1: Only writing "0" is effective. Writing "1" has no effect; the bit retains the value it had before the write.

Note: • TOP10 has only one interrupt source in the interrupt group, so that its status and mask registers are nonexistent in the MJT

interrupt control registers. (They are controlled directly by the Interrupt Controller.)
